What is Check Valves?
A check valve, also known as a non-return valve, one-way valve, or reflux valve, is a mechanical device designed to allow the flow of fluid (liquid or gas) in one direction only. The primary function of a check valve is to prevent backflow or reverse flow of the fluid, ensuring that it moves in the intended direction and does not return to its source. Check valves are used in various industries and applications to maintain the flow of fluids while preventing the risk of contamination, damage to equipment, or other undesired effects. Key Features and Components of Check Valves: Valve Body: The main body of the check valve houses the internal components and provides a passage for the fluid to flow through. The valve body is typically designed to be compatible with the specific application and the type of fluid being handled. Flapper, Disc, or Ball: The check valve mechanism includes a moving component such as a flapper, disc, or ball that responds to the flow of fluid.
